'1 claim.

This invention relates to a control whereby the width of gauze being woven on a loom is made substantially uniform.

It is an object of the invention to provide means which will assure substantially uniform width while at the same time the tension-is removed from the edges of the gauze during weaving.

Generally, as the amount of ller onfthe bobbin diminishes there is an increase lin the tension of the filler which in turn causes a variation in the width of the gauze which may amount to about one-half an inch.

It is a further objectof the invention to provide means which will counteract such tension variations which are due to variations in the amount of ller on the bobbin.

The uniformity of the width in gauze cloth is exceedingly important because during the tentering process unless the width is uniform there are large quantities of gauze which are damaged and rendered unfit for use. `It is an object of the invention, therefore, to provide` means which will assure absolute uniformity in the width of the gauze.

A still further object of the invention is to provide means which will eliminate any strain on the selvage thereby eliminating hoo-k selvages or kinks adjacent the selvages.

Furthermore, in certain processes the selvages are later removed and if there are hook` selvages or kinks such will cause ragged and uneven edges which would be very objectionable and would cause a further loss of material. It is an object of the invention to provide means which will eliminate these disadvantages.

A further object of the invention is to provide means associated with the reed cap and the temples which will cooperate with the selvages to secure the objects mentioned above.

With the above and other objects in view, which will appear from the detailed description below, the invention is shown in the drawing in which:

Fig. 1 is a side View of a portion of a loom showing the reed cap, reed, lay and a portion of one temple showing the invention as applied to the templeand the reed cap and illustrating in dotted lines the position occupied by the gauze width control when the lay is in its forward position.

Fig. 2 is a plan View of the parts shown in Fig. 1, and

Fig. 3 is a partial cross-sectional view illustrating the manner in which the gauze width control is mounted on its supporting base carried on the top cap of the temple.

Referring to the` drawing, in which similar to secure the gauze width control constituting the l0 present invention, to the temple.

TheY base plate upon which the control is mounted is indicated at I2 and comprises a top horizontalportion I3, a side portion I4 extending downwardly at right angles from the top por- 15 tion and a laterally extending ange portion I5 which is bent at right angles to the side portion I4.

A bearing I6 is secured to the side portion I4 of the base plate in any desired manner, prefer- 20 ably by threading, as shown at I1, and mounted on this bearing I 6 is an actuating lever I8 of L-shape. The upper portion of the upwardly directed stem I9 of the lever I8 is formed preferably of fiber as shown at 20 in order to eliminate excessive wear thereon. The ber end 20 is secured to the lever by means of a bolt 2 I.

'I'he actuating lever I8 is also provided with a substantial trunnion 22 positioned upon the bear- 30 ing I 6 and a nut 23 threaded upon the outer threaded end of the bearing I6 maintains the trunnion 22 and the actuating lever I8 in position on the bearing. A set screw 24 fixes the position of the nut 2'3 with relation to the bearing I6.

Encircling the trunnion 22 is a coil spring 25 having one end 26 positioned in a groove provided in the nut 23 and the other end 21 bearing against the top surface of the horizontally disposed stem of the actuating lever I8 so as to urge normally the lever I8 against the lateral flange I5 of the base plate, as shown in full lines in Fig. 1.

A projecting member 28, preferably integral with the actuating lever I8 extends at right angles inwardly from the stem I9 of the actuating lever and is disposed on the side opposite to that upon which the trunnion 22 is located. The projecting member has xed thereon at its inward free end the filler control 29 which is of the shape shown particularly in Fig. 1. The filler control is adjustably mounted in the projecting member and is xed in position by means of the set screw 30. The member 28 extends slightly above and parallel 'IQ J@he top cap 0i the 55 temple and when the actuating lever I8 isin the full line position of Fig. 1, the pointed end of the ller control 29 extends into the selvage of the gauze and supports the filler as the shuttle passes through the shed.

Upon the reed cap 'I there is secured by the screws 3|, a bracket 32 having spaced forwardly extending arms 33 in which the ber roller 34 is mounted by means of the bearing shaft 35.

The operation of the gauze Width control takes place as follows: Upon the forward movement of the lay 5 and thereed cap 1, the fiber roller 34 contacts the fiber end 20 of the actuating lever and pivots the lever to the dotted line position shown in Fig. 1 against the action of the spring 25 on its bearing I6. This pivoting o f the actuating lever also withdraws the pointed end of theY filler control 29 from the selvage and permits the reed 6 to beat up the filler. Upon the back- Ward movement of the lay with the reed, the spring 25 immediately returns the actuating lever I8 to the full line position of Figs. 1 and 2, so that the pointed end is in position to sustain the tension of the ller upon the next throw of the shuttle. It will be noted that the filler control 29, when in the full line position of Fig. 1, comes to rest at a slight distance Afrom the top cap of the temple and that in the return of the actuating lever the iiange I5 of the base plate I2 takes the blow. The filler control 29 is made adjustable in the projecting member 28 in order that it maybe compensated for any wear in the temple or associated parts. The trunnion 22 is made of considerable Width in order to provide room for a relatively large spring 25 which is necessary in order to stand up under the relatively heavy work since the actuating lever will be operated normally about 180 times a minute. It has been found that fiber is more satisfactory than metal in the operating roller 34 and the contact portion 20 of the actuating lever I8 although, of course, any desired material may be used in these locations.

As a rule, a plurality of slots may be provided in the nut 23 for the accommodation of the end 26 of the spring 25 so that a ner adjustment of the tension of such spring may be obtained.

With the exception of the relatively short time of the beat up, both filler control members 29 at each side of the gauze are in position so as to support the tension of the filler and remove such tension from the selvage ends.

I claim:

A gauze width control for looms comprising a base plate having a flange ymounted upon the temple of the loom, a bearing secured to said base plate, an actuating lever, a trunnion upon said actuating lever engaging said bearing, a coil spring encircling said trunnion and normally urging said actuating llever in contact with said flange, an extension upon said lever extending above and parallel to the top cap of said temple, o, ller control adjustably mounted in said eX- tension and a, Nroller Vmounted upon the reed cap of the loom adapted to engage said actuating lever to pivot the same and remove during the beatl u p said-filler `control from the cloth.
